This stuff is totally wacky. 8 ounce slubby light blue complext plaid. When you first see it, you think "Herb Tarlek!" But it grows on you. Or at least it did me. I've seen it made up, and it is gorgeous. 60% wool, 40% mohair.

3x3 means that yarns in both directions -- warp and weft -- are three ply. That is, each individual yarn used in the actual weaving is actually three twisted together. Sometimes it will say on the selvage. If in doubt, take some yarns from the cut end and carefully untwist them. If you can unravel one into three, in both directions, then it's 3x3.
